Hello everyone! I've been having some issues lately with Maya and QThread that I hope someone can help me, because I surely don't have any idea why that would be.
The crash I'm having is another variant of what Viktor Petrov asked here <https://stackoverflow.com/questions/56629553/proper-pyside-qthread-use-in-maya-to-avoid-hard-crash>, a sudden crash with no dialog or warning, just Maya closing unexpectedly. Inside of Maya I'm using a QThread that queries some data through HTTP requests (in my case specifically, this is done by the Ftrack <http://ftrack.com>API) and emits the result as a string through a signal. This tool works on Nuke as well and so far our Nuke users have not reported any issues of this kind. The crashes seem random but constant. There are no traceback or errors. I've gotten a process dump on the moment of the crash but to be honest either I don't know how to interpret it or it really doesn't help. I've also tried to switch to QRunnable + QThreadPool but doesn't solve the issue either. All data is interchanged as a string and I'm using a queue.Queue instance which should be thread safe. There is a small delay between the thread starting and the crash which leads me to think that the reason is either the result signal or the HTTP request itself. Is there any special precautions to use when dealing with QThread + HTTP requests in Maya? This is a slightly modified version of the code I'm using: https://gist.github.com/salvaom/c6df5b39d3a94667c19da20c4d223888#file-qthread1-py This is the code called from the main process, requestData is called to start a job and onThreadJobFinished is the callback when the thread finishes. The events have a unique ID to make sure no python object is sent to the thread, but that didn't solve the issue either. https://gist.github.com/salvaom/c6df5b39d3a94667c19da20c4d223888#file-qthread2-py I'm using Maya 2019, PySide2 - 2.0.0~alpha0, Qt - 5.6.1.
